A valid and probably simpler option would be to use this open source library by Monits https://github.com/Monits/blackberry-commons
It contains several common functionality found in BB applications and is compatible for BB 4.6.1+
Among other things, it provides a map field with the ability to add and display markers on top of it, with and without focus, and optionally "open" them. This makes for an API much more alike that found on other smart phones such as iPhone or Android.
The documentation is pretty good, and the wiki even has a tutorial on how to achieve it https://github.com/Monits/blackberry-commons/wiki/CustomMap
